Hair Brush

ABSTRACT

This brush is made up of: a handle ( 1 ); an aluminium tubular body ( 2 ) which is coated with an artificial plastic material, vinyl fluoride polymer, and holes ( 21 ) with polygonal shape, arranged in a herringbone pattern, which end in bevelling ( 21, 21   b ) and are arranged forming oblique lines in respect of the longitudinal axle of the brush; nylon fibres ( 41 ), ionized by means of radiation, fixed helicoidally to a supporting centre ( 4 ), located inside the tubular body, emerging the said fibres ( 41 ) through the holes ( 21 ) of the tubular body, and a front top ( 3 ) that closes the fore end of the above said tubular body.

OBJECT OF THE INVENTION

This invention is about a hair brush like the ones used for hair straightening and soft perms which feature: a handle, a holed tubular body through which emerge fibres that are fixed helicoidally to a support centre, and an upper top that closes the fore end of the said tubular body.

BACKGROUND OF THE INVENTION

Nowadays the use of hair brushes is common for hair brushing and soft perms either at home or in hairdressing and beauty salons. An example of commonly used brushes in hairdressing salons are the ones which comprise a hollow and holed tubular body which has got a handle for it to be held on one end and a top to close it on its other end being inside this tubular body a bunch of fibres arranged helicoidally which come out through the holes of the said tubular body. This kind of brushes allows making a soft perm and a hairdo while applying heat.

In these brushes the tubular body is made in aluminium coated or not with ceramic which allows the accumulation and transmission of calories provided by an external heat source, generally a hairdryer.

When the tubular body is coated with ceramic it accumulates calories for more time than just aluminium but transmits heat with less speed and effectiveness.

Another known inconvenient of this kind of brushes is that the hair products applied adhere on the tubular body little by little avoiding thus a smooth and uniform sliding of hair on the said tubular body.

Furthermore, another inconvenient of this kind of brushes lies in the fibres when emerging through the holes of the tubular body because they do not come out perpendicularly to it due to the fact that normally the holes are circular which cause most of the fibres to lean slightly avoiding the hair sliding smoothly over the brush and making effective contact with the surface of the tubular body, reducing thus the effectiveness of the brush notably, specially during the straightening and soft perm works. In this kind of brushes the holes of the tubular body are generally made by means of a die cut on an aluminium plate and during this process little imperfections remain all around the edges of the holes on one of the sides of the aluminium plate.

The presence of these imperfections becomes an important problem during the assembly of the different pieces that compound the brush or during the use of it, because in the case of these imperfections remaining at the internal side of the tube they become a means of retention for the fibres to come out through the tubular body, whereas in the case that the imperfections are on the external side of the tubular body they are so jagged that can damage the hair cuticle.

If it is preferred that the little imperfections are left on one concrete side of the tubular body, the aluminium plates from which the tubular bodies of the brushes will be shaped must be placed in a given position, then the imperfections can be all on the same side, but it slows down the manufacturing process.

DESCRIPTION OF THE INVENTION

The brush of this invention presents a series of technical features that allow a more effective and optimized use of it providing also a longer durability.

According to the invention, the brush features an aluminium tubular body holed and coated externally with an artificial plastic material with non-stick properties, with a high capacity of heat transmission and resistant to chemical and physical agents, being this material polytetrafluorethylene, also known as Teflon®.

Given that the aluminium is a good conductive material for heat, a homogeneous distribution of heat applied by means of a hair drier or similar can be achieved.

Furthermore, the coating of polytetrafluorethylene makes the time of heat transfer to be prolonged and provides a proper protection against the damage of the brush caused by the action of components in products applied on the hair, giving thus a longer useful life to the brush. Additionally, due to the non-stick properties of this coating material, a smooth sliding of hair over the tubular body of the brush is granted avoiding thus any pulling of the hair and also seals the hair cuticle obtaining thus as a result a more brilliant and reinforced hair than with the use of conventional brushes.

According to the invention, the holes made on the tubular body, through which the fibres come out, present a polygonal shape, in concrete a rhomboidal shape, and are arranged in a herringbone pattern so that the fibres can come out easily during the assembly of the brush. This feature also makes that the fibres are perpendicular to the tubular body providing thus a better brushing.

In order to facilitate even more the coming out of the fibres through the holes of the tubular body during the assembly of the brush, this brush presents specific characteristics, underlying: on one hand, that the holes are arranged in oblique lines in respect of the longitudinal axle of the brush, being the space between these polygonal holes equal or less than to 2 millimetres with which the weight of the brush is reduced as well as making it more handy and on the other hand, that the imperfections caused by the holes on both sides of the aluminium plate are bevelled. The internal bevelling favours the coming out of the fibre through the holes of the tubular body while the external bevelling avoids the presence of jagged imperfections on the external surface of the tubular body which can damage the hair cuticle.

The fibres of the brush are made of nylon ionized by means of radiation, which provides more strength and resistance to them during its use due to the alteration produced in their molecular structure during the radiation. The use of these ionized fibres favours the sliding of hair among them, avoiding the accumulation of static in the hair and therefore the undesirable effects that carries such accumulation.

FIGURE DESCRIPTION

In order to complete the present description done and with the aim to facilitate the understanding of the characteristics of the invention, a set of pictures is enclosed hereby in which with an illustrative end and not limitative, the following is represented:

FIG. 1 shows a sight of the raised brush sectioned longitudinally by a vertical plane.

FIG. 2 shows a sight of horizontal plane of a holed aluminium plate from which the tubular body of the brush is shaped.

FIG. 3 shows a transversal plane of the brush in a part coincident with the tubular body.

FIG. 4 shows a detail in perspective of the external bevelling of the holes on the tubular body.

FIG. 5 shows a transversal sectioning of one of the holes of the tubular body, allowing thus to observe the internal and external bevelling of the said hole.

PREFERRED CARRYING OUT OF THE INVENTION

As it can be seen in the said figures, the brush is featured by a handle (1) assembled by a mouthpiece to a tubular body (2) that is hollow with the surface holed, being closed the opposed side of this same tubular body (2) with a top (3) and being included a centre inside it (4) around which a bunch of fibres (41) is arranged helicoidally.

The fibres (41) come out through the holes (21) of the tubular body (2), being this fibres (41) made up of nylon bristles ionized through radiation.

The tubular body (2) is made of an aluminium plate coated externally with polytetrafluorethylene. The holes (21) present a rhomboid shape and are arranged in a herringbone pattern, forming oblique lines in respect of the longitudinal axle of the brush and with a space among them equal or less than 2 millimetres.

As it can be seen in FIGS. 4 and 5, the edges of the holes (21) either on the inside or the outside of the tubular body (2) are bevelled, ending these holes (21) in both respective bevelling (21 a and 21 b).

The internal bevelling favours the access of the fibres (41) to the holes (21) during the assembly of the brush and their coming out from it, while the external bevelling (21 b) avoids the jagged edges on the external surface of the tubular body (2) which may damage hair cuticle.

Once described sufficiently the aim of the invention, as well as an example of a preferred carrying out of the same, it is underlined that the materials, shape, size and disposition of the described elements can be modified, provided that it do not mean an alteration of the characteristics of the invention which are claimed as follows.
